I am an Assistant Professor in the Department of Government at Dartmouth College. My research interests include nuclear proliferation and international security. My book, Stopping the Bomb: The Sources and Effectiveness of U.S. Nonproliferation Policy, was published by Cornell University Press in 2018. The dissertation on which the book is based received the 2015 Helen Dwight Reid Award, awarded by the American Political Science Association for the best dissertation in international relations, law, and politics. It also won the 2015 Kenneth N. Waltz Prize, awarded for the best dissertation in the field of international security and arms control.

My research has been published in the American Political Science Review, International Organization, International Security, ​International Studies Quarterly, the Journal of Conflict Resolution, and Security Studies. Some of my other work has been published at the Washington Post/Monkey Cage, Lawfare, Foreign Affairs, The National Interest, Politico, War on the Rocks, and on ForeignPolicy.com.

I received my PhD in Political Science from MIT and am a research affiliate at the MIT Security Studies Program. Before coming to Dartmouth, I was an Assistant Professor at Brown University. I originally hail from Midcoast Maine.
